XML Tree Viewer
Parse raw XML strings into an interactive DOM tree. Features syntax highlighting, error validation, and XPath generation for debugging nested structures.
About
Reading raw XML responses or configuration files typically leads to eye strain and missed syntax errors. Developers working with legacy SOAP APIs or complex data interchanges require a clear visualization of the Document Object Model. This tool parses the XML string and renders it as a hierarchical tree. It highlights node relationships and attribute values to ensure data integrity.
The parsing engine utilizes the native browser implementation to validate structure. It detects unclosed tags or invalid characters that often break downstream parsers. Users can navigate deeply nested elements by collapsing or expanding branches. The integrated XPath generator aids in writing precise queries for scraping or automated testing frameworks. Accuracy in the document structure is paramount for system interoperability.
Formulas
When calculating the complexity or navigating the depth of an XML tree, we consider the nesting level L and the branching factor b. The maximum number of nodes N in a perfectly balanced tree structure is defined by the geometric series:
XPath indexing relies on the sibling position i of a specific tag type. If a parent node P contains multiple children of type T, the path is denoted as:
